Description

  The present invention relates to a vehicle door operation mechanism capable of releasing door closing and holding (hereinafter referred to as “door latch” as appropriate) by a latch / ratchet mechanism using the power of a motor.

  In this type of vehicle door operation mechanism, if the motor fails while the door latch is released, the door cannot be latched again. As a conventional vehicle door operation mechanism that can cope with such an emergency, there is known a vehicle door operation mechanism that includes a motor separation operation unit inside the door. In this vehicle door operation mechanism, a tool is inserted into an operation hole formed through the door and the motor disconnecting operation unit is operated, so that the motor is disconnected from the latch / ratchet mechanism in the above-described emergency state so that the door can be latched. It can be restored (see, for example, Patent Document 1).

JP 2010-31569 A (paragraphs [0079] and [0080] FIGS. 11 to 13)

  However, since the conventional vehicle door operation mechanism described above does not know the existence of the motor disconnection operation part and its operation hole, it is strongly recommended to contact repair personnel or to check the vehicle manual in an emergency. As a result, a situation in which the door cannot be quickly returned to a latchable state may occur. Further, even if the user knows the existence of the motor disconnection operation portion and its operation hole, it is difficult to quickly return to the door latchable state because it is difficult to operate through the operation hole.

  The present invention has been made in view of the above circumstances, and in an emergency where the door cannot be closed due to a motor failure or the like, the door can be quickly returned to a state where the door can be closed. The object is to provide a vehicle door operating mechanism.

In order to achieve the above object, the vehicle door operating mechanism according to the invention of claim 1 is interlocked with the ratchet of the latch / ratchet mechanism for holding the door of the vehicle in the closed state, and releases the closed holding by the latch / ratchet mechanism. When the main support shaft is rotated, the ratchet interlocking lever that rotates about the main support shaft from the origin position in the first rotation direction and the operation power generated by the opening operation of the outside operation handle arranged on the outdoor surface of the door are received. Is rotated in the first rotation direction from the origin position, and the outside handle interlocking lever capable of applying power in the first rotation direction to the ratchet interlocking lever and the opening of the in-vehicle operation handle disposed on the indoor surface of the door. in response to operation power by operating to pivot in a first rotational direction of the main support axis from the origin position, ratchet power facing first rotation direction without passing through the outside handle interlocking lever Together and a preparative interlocking lever allows imparting a vehicle handle interlocking lever, a release motor is connected to the outside of the vehicle handle interlocking lever, the motor power release motor has output due to the opening operation of the car operating handle or outside the operating handle, In the vehicle door operation mechanism that can assist the release of the door closing hold by applying the power to the ratchet interlocking lever as the power in the first rotation direction via the vehicle outer handle interlocking lever, the ratchet interlocking from the vehicle outer handle interlocking lever It operates in accordance with the locking / unlocking operation of the indoor lock operation part provided in the middle of the power transmission path to the lever and arranged on the indoor surface of the door, and changes the first rotation direction from the vehicle exterior handle interlocking lever to the ratchet interlocking lever. It is possible to move between the power transmission position that transmits the motive power and the power cutoff position that interrupts the transmission of the power. Characterized in place with power relay member.

  According to a second aspect of the present invention, in the vehicle door operation mechanism according to the first aspect, an L-shaped first side path formed in one of the ratchet interlocking lever and the vehicle exterior handle interlocking lever and extending in the rotational radius direction. L-shaped long hole that extends from the one end of the arc-shaped L-shaped second side path centered on the main support shaft, and the other lever of the ratchet interlocking lever and the outside handle interlocking lever, and the ratchet interlocking The I-shaped elongated hole that overlaps the L-shaped first side path with both the lever and the vehicle exterior handle interlocking lever arranged at the origin position, and the I-shaped elongated hole and the L-shaped elongated hole are both penetrated.

[Invention of Claim 1]
According to the first aspect of the present invention, when the power relay member is moved to the power cut-off position by operating the indoor lock operating portion while the door is closed and closed, the transmission of power from the vehicle exterior handle interlocking lever to the ratchet interlocking lever is performed. Blocked. Thereby, even if the outside handle is operated on the outside of the door, the door cannot be opened. On the other hand, when the power relay member is moved to the power transmission position by operating the indoor lock operation section, it becomes possible to transmit the power directed in the first rotation direction from the vehicle exterior handle interlocking lever to the ratchet interlocking lever. The door can be opened by operating the handle outside the vehicle. In addition, if the power relay member is disposed at the power transmission position, the motor power from the release motor is applied to the vehicle exterior handle interlock lever when the vehicle operation handle or vehicle exterior operation handle is opened while the door is closed and held. Is transmitted to the ratchet interlock lever. As a result, it is possible to release the door closed holding with the assistance of the release motor.

  Here, due to a failure of the release motor, an abnormality in the transmission path of the motor power, etc., the vehicle exterior handle interlock lever stops abnormally at the rotation end position in the first rotation direction and stops moving, and the door cannot be closed and held. In an emergency, the power relay member may be moved from the power transmission position to the power cut-off position by operating the indoor lock operation section. Then, as described above, the transmission of power from the vehicle exterior handle interlocking lever to the ratchet interlocking lever is interrupted, and as a result, the release motor having an abnormality in the motor power transmission path or the failed release motor is removed from the latch / ratchet mechanism. Disconnected. As a result, the ratchet interlocking lever and the ratchet can return to the origin position, and the door is returned to a state in which the door can be kept closed.

  As described above, according to the vehicle door operation mechanism of the present invention, since the indoor lock operation unit that is normally used for the door locking / unlocking operation is also used as the operation target of the motor disconnection operation, In the event of an emergency when it is impossible to keep the door closed, it is possible to quickly return to a state in which the door can be kept closed by operating the indoor lock operation unit by trial and error without examining the vehicle manual. In addition, since a tool is not required for the motor separating operation as in the prior art, the door can be quickly returned to a state where it can be kept closed. Also, if the in-vehicle operation handle is opened in the same way as normal with the door closed by the motor disconnection operation, power is applied from the in-vehicle handle interlocking lever to the ratchet interlocking lever, and the door closing retention is released. It is possible to open the door.

For example, the sliding door 90 is retracted obliquely backward from a state in which the elevator opening of the vehicle main body 99 is closed, and is receded straight from the middle to be fully opened. In order to open and close the slide door 90, an exterior operation handle 17 (see FIG. 5) is disposed on the exterior surface of the slide door 90, and an interior operation handle 18 (see FIG. 2) is disposed on the interior surface. The outside operation handle 17 is, for example, a grip type handle and is operated by pulling it toward the front side. The indoor surface of the slide door 90 is provided with an indoor lock operation portion 16 for locking the slide door 90 so that the slide door 90 does not open even if the outside operation handle 17 and the inside operation handle 18 are opened. The in-vehicle operation handle 18 and the indoor lock operation unit 16 will be described later.

  As shown in FIG. 2, the slide door 90 includes a front door lock device 10 </ b> A and a rear door lock device 10 </ b> B for holding the slide door 90 in a closed state, and a fully open door lock for holding the slide door 90 in a fully open state. A device 10C and a remote control device 100 connected to the door lock devices 10A, 10B, and 10C are provided.

  The door lock devices 10A, 10B, and 10C are disposed at predetermined positions on the slide door 90, and correspondingly, strikers 40 are provided at three positions on the inner surface of the door frame 99W (the frame of the lift). (Only two strikers 40 are shown in FIG. 1).

  As shown in FIG. 3, the front door lock device 10 </ b> A has a structure in which a latch / ratchet mechanism 20 </ b> K having a latch 20, a ratchet 30, a striker receiving groove 12 and the like is provided on the base board 11.

  The striker receiving groove 12 extends in the horizontal direction, and one end thereof is open toward the vehicle inner side, and the other end is closed. When the slide door 90 is closed, the striker 40 enters the striker receiving groove 12 from one end of the striker receiving groove 12.

  A ratchet 30 is rotatably supported below the striker receiving groove 12 in the base board 11. The ratchet 30 protrudes toward the latch 20 from the rotation shaft 30J. A torsion coil spring 30S is provided between the ratchet 30 and the base board 11, and the ratchet 30 is urged counterclockwise in FIG. 3 by the torsion coil spring 30S. The ratchet 30 is integrally provided with a ratchet drive lever 30R on the opposite side across the base board 11, and the ratchet drive lever 30R and the remote control device 100 are connected by an open cable 91W. The open cable 91W is pulled toward the ratchet 30 by the torsion coil spring 30S. When the open cable 91W is pulled toward the remote control device 100 against the urging force of the torsion coil spring 30S, the ratchet 30 rotates in the clockwise direction in FIG. To turn.

  A latch 20 is rotatably supported above the striker receiving groove 12 in the base board 11. The latch 20 includes a pair of locking claws 21 and 22, and a striker receiving portion 23 is formed between the locking claws 21 and 22. The latch 20 is biased in the latch release direction (clockwise direction in FIG. 3) by a torsion coil spring 20S provided between the latch 20 and the base board 11. When the slide door 90 is opened, the latch 20 is positioned at one end in the latch release direction as shown in FIG.

  When the sliding door 90 is slid in the closing direction in this state, the striker 40 that has entered the striker receiving groove 12 is received in the striker receiving portion 23 of the latch 20 as shown in FIG. When the latching claw 22 is pushed, the latch 20 rotates in the latch direction (counterclockwise direction in FIG. 3) opposite to the latch release direction. As a result, the latch 20 is engaged with the striker 40 as shown in FIG.

  At this time, the ratchet 30 comes into contact with the latching claw 21 on the front side of the latch 20, and the latch 20 is prohibited from rotating in the latch release direction (clockwise direction in FIG. 4). That is, the latch 20 is held in a state of being engaged with the striker 40.

  Further, when the outside operation handle 17 or the inside operation handle 18 is opened while the latch 20 and the striker 40 are engaged with each other (the slide door 90 is held closed), the open cable 91W is pulled toward the remote control device 100. Then, as indicated by a two-dot chain line in FIG. 4, the ratchet 30 rotates in the clockwise direction in FIG. 4, retracts to the outside of the rotation area of the latch 20, and the ratchet 30 restricts the rotation of the latch 20.

The rear door lock device 10B is also provided with a latch / ratchet mechanism (not shown) that operates in the same manner as the front door lock device 10A. The ratchet of the rear door lock device 10B and the remote control device 100 are connected by an open cable 92W (see FIG. 2), and when the outside operation handle 17 or the inside operation handle 18 of the slide door 90 is opened, the opening is performed. The cable 92 </ b> W is pulled toward the remote control device 100, so that the latch rotation restriction by the ratchet is released.

  Then, in the latch and ratchet mechanism 20K of both the front door lock device 10A and the rear door lock device 10B, when the latch 20 and the striker 40 are held in the engaged state (the state shown in FIG. 4) by the ratchet 30, The slide door 90 is held in a closed state (door latch). In addition, in the latch and ratchet mechanism 20K of both the front door lock device 10A and the rear door lock device 10B, when the rotation restriction of the latch 20 by the ratchet 30 is released, the closed holding of the slide door 90 is released, The slide door 90 can be opened (slid in the opening direction).

  Similarly to the front door lock device 10A, the fully open door lock device 10C is provided with a latch / ratchet mechanism. When the slide door 90 is fully opened, the latch and the ratchet mechanism are engaged with the latch and the striker 40, and the ratchet is brought into contact with the latch to restrict the rotation in the latch release direction. The ratchet of the fully open door lock device 10C and the remote control device 100 are connected by an open cable 93W (see FIG. 2).

  When the outside operation handle 17 or the inside operation handle 18 is closed while the slide door 90 is fully open, the open cable 93W is pulled to the remote control device 100 side. Then, the latching restriction of the latch by the ratchet is released, and the fully open slide door 90 can be closed (slid in the closing direction).

  Now, as shown in FIG. 2, the remote control device 100 is disposed at a position near the front end of the slide door 90. In addition, as shown in FIG. 5, the remote control device 100 has a configuration in which a mechanism door 101 is provided with a vehicle door operation mechanism 100K.

  As shown in FIG. 6, an in-vehicle operation handle 18 and an indoor lock operation unit 16 are provided on the surface of the mechanism panel 101 opposite to the vehicle door operation mechanism 100K. The mechanism panel 101 is fixed so that the surface on which the in-vehicle operation handle 18 and the indoor lock operation unit 16 are provided is directed to the indoor door panel of the slide door 90 from the inside.

  The in-vehicle operation handle 18 has a vertically long structure extending in the vertical direction, and is exposed on the interior surface of the slide door 90. The in-vehicle operation handle 18 can tilt in the sliding direction of the slide door 90. Specifically, the in-vehicle operation handle 18 is biased to the origin position shown in FIG. 6 by a torsion coil spring 18A (see FIG. 5), and the sliding door 90 is closed from the origin position on the closing direction side (left side in FIG. 6). It is possible to perform a closing operation for tilting to an open position and an opening operation for tilting from the origin position to the opening direction side of the slide door 90 (right side in FIG. 6).

  The indoor lock operation unit 16 is disposed below the in-vehicle operation handle 18 and is exposed on the indoor surface of the slide door 90. The indoor lock operation unit 16 is movable in the sliding direction of the slide door 90. As will be described in detail later, when the indoor lock operation unit 16 is moved from the position shown in FIG. 6 toward the closing direction of the slide door 90, the in-car operation handle 18 and the out-of-vehicle operation handle 17 cannot open the slide door 90. Will be locked. Conversely, when the indoor lock operation unit 16 is moved to the opening direction side of the slide door 90 to the position shown in FIG. 6, the slide door 90 can be opened by the in-vehicle operation handle 18 or the out-of-vehicle operation handle 17. It will be unlocked. Hereinafter, the operation of moving the indoor lock operation unit 16 toward the closing direction of the slide door 90 is referred to as “locking operation”, and the operation of moving the indoor lock operation unit 16 toward the opening direction of the slide door 90 is referred to as “unlocking”. This is called “operation”.

  As shown in FIG. 5, the vehicle door operation mechanism 100 </ b> K overlaps the vehicle exterior handle interlocking lever 120, the ratchet interlocking lever 130, the vehicle interior handle interlocking lever 140, and the fully open lock lever 170 in order from the side closer to the mechanism panel 101. The main support shaft 102 erected from the mechanism panel 101 is pivotally supported, and the locking lever 180 is pivotally supported on the sub-support shaft 103 (see FIG. 6) erected from the mechanism panel 101. ing. For example, the locking lever 180 is made of resin, and the other levers 120 to 140, 170 are made of metal. Hereinafter, the vehicle door operation mechanism 100K will be described in detail.

  FIG. 7 shows a main part of the vehicle door operation mechanism 100K. As shown in the figure, the fully open lock lever 170 has a pair of lever protrusions 171 and 172 projecting in the opposite direction from the main support shaft 102. One lever protrusion 172 is connected to a ratchet of a fully open door lock device 10C via an open cable 93W (see FIGS. 2 and 5). The other lever protruding piece 171 is formed with an arc-shaped long hole 175 centering on the main support shaft 102. A slide bush 175B is slidably supported in the long hole 175, and the end of the rod 105 extending from the in-vehicle operation handle 18 is fixed to the slide bush 175B (see FIG. 5). When the in-vehicle operation handle 18 is closed (tilt leftward in FIG. 6), the rod 105 is pushed to the fully open lock lever 170 side. Then, as shown in the change from FIG. 7 to FIG. 10, the fully open lock lever 170 rotates around the main support shaft 102 from the origin position in the first rotation direction (clockwise direction in FIG. 7). As a result, the open cable 93W connected to the lever protrusion 172 is pulled toward the remote control device 100, and the latch rotation restriction by the ratchet of the fully open door lock device 10C is released. When the in-vehicle operation handle 18 is opened, the rod 105 is pulled toward the in-vehicle operation handle 18, but the slide bush 175B moves in the long hole 175, so that the fully open lock lever 170 remains at the origin position shown in FIG. .

  The fully open lock lever 170 is integrally formed with a switch pressing protrusion 174. The switch pressing protrusion 174 protrudes toward the switch 110 (see FIG. 5) fixed to the mechanism panel 101, and the switch pressing protrusion 174 when the fully open lock lever 170 rotates in the first rotation direction. Presses the switch 110.

  As shown in FIG. 7, the in-vehicle handle interlocking lever 140 is overlapped with the lever protrusion 172 in the fully open lock lever 170. As shown in FIG. 8, an arc-shaped long hole 142 centering on the main support shaft 102 is formed through the front end portion of the in-vehicle handle interlocking lever 140 away from the main support shaft 102. A slide bush 142B is slidably supported in the long hole 142, and the end of the rod 106 extending from the in-vehicle operation handle 18 is fixed to the slide bush 142B (see FIG. 5). Further, the in-vehicle handle interlocking lever 140 has a second rotation direction (FIG. 8) opposite to the first rotation direction by a coil spring 145 (see FIGS. 5 and 6) connected to the mechanism panel 101. In the counterclockwise direction).

  When the in-vehicle operation handle 18 is opened (tilted in the right direction in FIG. 6), the rod 106 is pulled toward the in-vehicle operation handle 18 side. Then, as shown in the change from FIG. 8 to FIG. 11, the vehicle interior handle interlocking lever 140 rotates about the main support shaft 102 in the first rotation direction (clockwise direction in FIG. 8). When the in-vehicle operation handle 18 is closed, the rod 106 is pushed toward the in-vehicle handle connecting lever 140, but the slide bush 142B moves in the elongated hole 142, so that the in-vehicle handle interlocking lever 140 is located at the origin position shown in FIG. Stay on.

  A switch pressing protrusion 143 is integrally formed with the in-vehicle handle interlocking lever 140. The switch pressing protrusion 143 protrudes toward the switch 111 (see FIG. 5) fixed to the mechanism panel 101. When the in-vehicle handle interlocking lever 140 rotates in the first rotation direction, the switch pressing protrusion 143 A piece 143 presses the switch 111.

  By the way, in the state in which the slide door 90 is closed and held, a soundproof member (not shown) is crushed between the slide door 90 and the door frame 99W, and the reaction force causes the front door lock device 10A and the rear door lock. Each ratchet 30 of the device 10B and the latch 20 are in frictional engagement. On the other hand, in order to open the slide door 90, it is necessary to turn both the ratchets 30 of the front door lock device 10A and the rear door lock device 10B against the frictional resistance between the ratchet 30 and the latch 20, and the manual operation. Thus, a large force is required to rotate both the ratchets 30 (to release the door latch to the latch / ratchet mechanism 20K).

  Therefore, the remote control device 100 is provided with a release motor 60 (see FIG. 5) for assisting the release of the door latch by the latch / ratchet mechanism 20K, and the motor power is linked to the ratchet via the outside handle interlocking lever 120. It is transmitted to the lever 130. The release motor 60 operates due to the opening operation of the in-vehicle operation handle 18 or the out-of-vehicle operation handle 17. It can also be activated by remote control such as remote control keys.

  As shown in FIG. 8, the vehicle exterior handle interlocking lever 120 extends from the main support shaft 102 toward the side opposite to the vehicle interior handle interlocking lever 140. A pair of long holes 121 and 122 are formed through the distal end portion of the vehicle exterior handle interlocking lever 120 away from the main support shaft 102. Both the long holes 121 and 122 have an arc shape with the main support shaft 102 as the center, and slide bushes 121B and 122B are slidably supported on the inner side (see FIG. 5).

  The end of the open cable 95W extending from the release motor 60 is connected to the slide bush 122B supported by the long hole 122 closer to the main support shaft 102 of the vehicle exterior handle interlocking lever 120 (see FIG. 5). . When the release motor 60 is operated, the open cable 95W is pulled toward the release motor 60 by the motor power. Accordingly, the vehicle exterior handle interlocking lever 120 is rotationally driven in the first rotation direction (clockwise direction in FIG. 9).

  Further, as shown in FIG. 5, the end of an open cable 94 </ b> W extending from the outside operation handle 17 is connected to the slide bush 121 </ b> B supported by the long hole 121 far from the main support shaft 102. When the outside operation handle 17 is opened (pulled forward), the open cable 94W is pulled to the outside operation handle 17 side by the operation power, and the outside handle interlocking lever 120 moves around the main support shaft 102 in the first rotation direction. It is designed to rotate. That is, the vehicle exterior handle interlocking lever 120 receives both the motor power of the release motor 60 and the operation power generated by the opening operation of the vehicle exterior operation handle 17 and rotates in the first rotation direction.

  An L-shaped long hole 123 is formed through the outer handle interlocking lever 120 in a portion closer to the main support shaft 102 than the pair of long holes 121 and 122. As shown in FIG. 9, the L-shaped long hole 123 has an L-shaped first side path 123A extending in the rotational radius direction and an end portion of the L-shaped first side path 123A away from the main support shaft 102. It comprises an L-shaped second side path 123B extending in the second rotation direction. A connecting pin 134 described later passes through the L-shaped long hole 123.

  Here, from the side edge portion of the vehicle exterior handle interlocking lever 120 facing the first rotation direction, the interlocking contact protrusion 125 is at a right angle toward the fully open lock lever 170 (toward the front side in FIG. 9). It is bent up. Corresponding to this interlocking contact protrusion 125, from the side edge portion of the lever protrusion 171 of the fully open lock lever 170 facing the first rotation direction side, the vehicle exterior handle interlocking lever 120 is moved as shown in FIG. The interlocking contact protrusion 173 is bent and raised at a right angle (toward the rear side of the sheet of FIG. 7).

  When the vehicle handle interlock lever 120 rotates around the main support shaft 102 in the first rotation direction by the motor power of the release motor 60 or the operation power generated by opening the vehicle operation handle 17, the interlocking contact protrusions 125 and 173 are connected to each other. , The fully open lock lever 170 is pushed by the vehicle exterior handle interlocking lever 120, and both the levers 120 and 170 rotate integrally in the first rotation direction. Further, when the interlocking contact protrusions 125 and 173 are in contact with each other, the vehicle exterior handle interlocking lever 120 receives the biasing force of the coil spring 176 via the fully open lock lever 170, and is attached in the second rotation direction. Be forced. The vehicle handle interlock lever 120 and the fully open lock lever 170 are positioned at the origin position (see FIGS. 7 and 8) where the vehicle handle interlock lever 120 contacts the stopper 104 (see FIG. 5) of the mechanism panel 101. Yes.

  As shown in FIG. 9, the ratchet interlocking lever 130 has a pair of lever protrusions 131 and 132 extending from the main support shaft 102 in opposite directions. Of the pair of lever protrusions 131 and 132, a front door lock device is connected to the tip of the lever protrusion 131 extending on the same side as the lever protrusion 172 of the fully open lock lever 170 via open cables 91W and 92W. The ratchets 30 of 10A and the rear door lock device 10B are connected (see FIG. 5).

  Of the pair of lever protrusions 131 and 132, an I-shaped long hole 133 extending in the rotational radius direction is formed through the tip of the lever protrusion 132 that overlaps with the vehicle exterior handle interlocking lever 120. The I-shaped long hole 133 is formed in a portion of the lever protruding piece 132 that is closer to the distal end away from the main support shaft 102. The I-shaped long hole 133 can be overlapped with the L-shaped first side path 123A of the L-shaped long hole 123 when both the vehicle exterior handle interlocking lever 120 and the ratchet interlocking lever 130 are located at the origin position. A common connecting pin 134 passes through the mold long hole 133 and the L long hole 123. The connecting pin 134 is supported by the I-shaped long hole 133 and is guided by a pair of sides extending in the longitudinal direction of the I-shaped long hole 133 so that the connecting pin 134 extends in the longitudinal direction of the I-shaped long hole 133 and the L-shaped long hole 134. It can be reciprocated. The connecting pin 134 has a circular cross section, but may have a rectangular cross section corresponding to the width of the straight long hole 133. The connecting pin 134 corresponds to the “power relay member” of the present invention.

  As shown in FIG. 9, a power transmission protrusion 136 is integrally formed with the ratchet interlocking lever 130. The power transmission projecting piece 136 is disposed in front of the in-vehicle handle interlocking lever 140 in the first rotation direction. The tip of the power transmission protrusion 136 is bent to the in-vehicle handle interlocking lever 140 side (the front side of the paper in FIG. 9) and contacts the in-vehicle handle interlocking lever 140 rotated in the first rotational direction from the origin position. It is possible. That is, when the in-vehicle operation handle 18 is opened, the ratchet interlocking lever 130 is rotated in the first rotation direction by being pushed by the in-vehicle handle interlocking lever 140.

  A torsion coil spring 129 is provided between the power transmission projecting piece 136 and the main support shaft 102, and the ratchet interlocking lever 130 is attached in the second rotation direction (counterclockwise direction in FIG. 9) by the torsion coil spring 129. It is energized. Then, the ratchet interlocking lever 130 is positioned at the origin position shown in FIG. 8 by the stopper 135 provided at the tip of the lever protrusion 131 coming into contact with the mechanism panel 101 (see FIGS. 5 and 6). In addition, the vehicle interior handle interlocking lever 140 and the power transmission projecting piece 136 are disposed so as to be close to each other or in contact with each other while being located at the origin position.

  As shown in FIG. 9, a switch pressing protrusion 138 is integrally formed with the ratchet interlocking lever 130. The switch pressing protrusion 138 protrudes toward the switch 111 (see FIG. 5) fixed to the mechanism panel 101. When the ratchet interlocking lever 130 rotates in the first rotation direction, the switch pressing protrusion 138 A switch 111 is pressed. When the switch pressing protrusion 138 presses the switch 111, it is detected that the in-vehicle operation handle 18 or the out-of-vehicle operation handle 17 is opened.

  As shown in FIG. 5, the mechanism panel 101 is assembled with a locking lever 180 and a locking actuator 185 for moving the connecting pin 134 in the longitudinal direction of the I-shaped long hole 133. The locking lever 180 has a lever protrusion 181 protruding from the sub support shaft 103 toward the locking actuator 185, and a lever protrusion 182 protruding from the sub support shaft 103 toward the connecting pin 134 (FIG. 9). reference).

  One lever protruding piece 182 in the locking lever 180 is formed with an arc-shaped connecting pin through long hole 183. The connecting pin penetrating elongated hole 183 can be overlapped with the I-shaped elongated hole 133 and the L-shaped elongated hole 123, and the connecting pin 134 is movably penetrated therethrough.

  The locking actuator 185 is mainly composed of an electric motor that operates by remote operation (for example, operation of a remote control key or a central door lock button in the vehicle), and its output lever 186 (see FIG. 5) is a lever protrusion 181 of the locking lever 180. And a pin (not shown) and a long hole 184. In addition, the output lever 186 and the indoor lock operation unit 16 are connected so that the output lever 186 reciprocates by the locking / unlocking operation of the indoor lock operation unit 16 (see FIG. 5).

  When the locking / unlocking operation of the indoor lock operation unit 16 is performed or the locking actuator 185 is activated, the locking lever 180 rotates around the sub support shaft 103, and the connecting pin 134 is the main support shaft of the I-shaped long hole 133. The power transmission position at the end on the 102 side (the position indicated by the solid line in FIG. 8) and the power cutoff position at the end on the L-type second side path 123B side of the I-shaped long hole 133 (in the two-dot chain line in FIG. 8) Move to the position shown).

  For example, when the unlocking operation of the indoor lock operation unit 16 is performed, the locking lever 180 is rotated about the sub support shaft 103 in the clockwise direction in FIG. 8 by the operation power, and the connecting pin 134 is moved from the power cutoff position to the power transmission position. Move to. In this power transmission position, the connecting pin 134 passes through the I-shaped long hole 133 and the L-shaped first side path 123A, so that the ratchet interlocking lever 130 and the vehicle exterior handle interlocking lever 120 are connected to each other by the connecting pin 134 so as to be integrally rotatable. Is done.

  On the other hand, for example, when the indoor lock operation unit 16 is locked (moving in the closing direction of the slide door 90), the locking lever 180 rotates around the sub support shaft 103 in the counterclockwise direction in FIG. As a result, the connecting pin 134 moves from the power transmission position to the power cutoff position. At this time, the connecting pin penetrating long hole 183 overlaps with the L-shaped second side path 123B, and the connecting pin 134 passes through the I-shaped long hole 133 and the L-shaped second side path 123B to enter the L-shaped second side path 123B. Can be moved in the longitudinal direction. That is, the vehicle exterior handle interlocking lever 120 and the ratchet interlocking lever 130 are separated so as to be relatively rotatable. Therefore, when the vehicle exterior handle interlocking lever 120 rotates around the main support shaft 102 in the first rotational direction, the power is not transmitted to the ratchet interlocking lever 130, and the ratchet interlocking lever 130 is at the origin position shown in FIG. Will stay.

  The configuration of the present embodiment is as described above. Next, the operation of the vehicle door operation mechanism 100K will be described. When the in-vehicle operation handle 18 is closed from the origin position (tilted in the closing direction) when the slide door 90 is fully open, the rod 105 moves directly by the operation power, and the change from FIG. 7 to FIG. As shown, the fully open lock lever 170 is pushed around the main support shaft 102 in the first turning direction by being pushed by the rod 105. Then, the open cable 93W (see FIG. 5) connected to the fully open lock lever 170 (lever protrusion 172) is pulled toward the remote control device 100, and the slide door 90 is held fully open by the latch / ratchet mechanism of the fully open door lock device 10C. Is released. Thereby, the slide door 90 can be slid in the closing direction from the fully open state.

  When the outside operation handle 17 is closed (pulled forward) when the slide door 90 is fully opened, the open cable 94W is pulled by the operation power, and the outside handle interlocking lever 120 moves around the main support shaft 102 for the first time. The interlocking contact protrusion 125 of the vehicle exterior handle interlocking lever 120 pushes the interlocking contact protrusion 173 of the fully open lock lever 170 in the first rotational direction. Thereby, the fully open lock lever 170 rotates in the first rotation direction, and the fully open holding of the slide door 90 by the fully open door lock device 10C is released.

  When the sliding door 90 is fully opened, if the remote operation (operating the remote control key or the door opening / closing button in the vehicle) is performed without operating the in-vehicle operation handle 18 or the out-of-vehicle operation handle 17, the release motor 60 is activated. In response to the motor power, the vehicle handle interlock lever 120 is driven to rotate in the first rotation direction. Then, the fully open lock lever 170 is pushed by the vehicle handle interlock lever 120 and rotates in the first rotation direction, and the fully open holding of the slide door 90 by the fully open door lock device 10C is released.

  Next, the vehicle door operation mechanism 100K in the case where the door lock is unlocked (the connecting pin 134 is the power transmission position) and an operation for opening the slide door 90 closed and held by the latch / ratchet mechanism 20K is performed. The operation will be described.

  As shown in the change from FIG. 8 to FIG. 11, when the in-vehicle operation handle 18 is opened from the origin position, the in-vehicle handle interlocking lever 140 is rotated in the first rotation direction in response to the operation power, and the in-vehicle handle Pushed by the interlocking lever 140, the ratchet interlocking lever 130 rotates in the first rotation direction. Further, the release motor 60 is actuated due to the opening operation of the in-vehicle operation handle 18 (pressing of the switch 111 by the ratchet interlocking lever 130), and the out-of-vehicle handle interlocking lever 120 is rotationally driven in the first rotation direction. Then, the motor power of the release motor 60 is transmitted to the ratchet interlocking lever 130 via the vehicle exterior handle interlocking lever 120, and the rotation of the ratchet interlocking lever 130 in the first rotational direction is assisted by the motor power of the release motor 60. The

  As the ratchet interlocking lever 130 rotates in the first rotation direction, the open cables 91W and 92W are pulled toward the remote control device 100 side. When the ratchet interlocking lever 130 and the vehicle exterior handle interlocking lever 120 reach the rotation end position (position shown in FIG. 11) separated from the origin position in the first rotation direction, the front door lock device 10A and the rear door lock In each latch and ratchet mechanism 20K of the apparatus 10B, the rotation restriction of the latch 20 by the ratchet 30 is released (see FIG. 3). That is, with the assistance of the release motor 60, the closed holding of the slide door 90 is released, and the slide door 90 can be slid in the opening direction.

  As shown in the change from FIG. 8 to FIG. 12, when the outside operation handle 17 is opened (pulled forward), the outside handle interlocking lever 120 and the ratchet interlocking lever 130 are moved in the first rotation direction by the operation power. Rotates together. Further, the release motor 60 is actuated due to the opening operation of the vehicle exterior operation handle 17 (the switch 111 is pressed by the ratchet interlocking lever 130), and the vehicle exterior handle interlocking lever 120 is rotationally driven in the first rotation direction. Thereafter, as in the case of opening the in-vehicle operation handle 18, the ratchet interlocking lever 130 is rotated to the rotation end position in the first rotation direction with the assistance of the release motor 60, and the front door lock device 10A and the rear The closed holding of the slide door 90 by each latch / ratchet mechanism 20K provided in the side door lock device 10B is released.

  When the remote operation is performed by the remote control key or the door opening / closing button instead of the opening operation of the in-vehicle operation handle 18 or the out-of-vehicle operation handle 17, the release motor 60 is moved from the origin position to the rotation end position in the first rotation direction. The outside handle interlocking lever 120 and the ratchet interlocking lever 130 are rotationally driven only by the motor power of the motor. Then, as described above, the closed holding of the slide door 90 by the latch and ratchet mechanisms 20K of the front door lock device 10A and the rear door lock device 10B is released.

  When the in-vehicle operation handle 18 is opened when the door lock is locked (the position of the connecting pin 134 indicated by the two-dot chain line in FIG. 8), the in-vehicle handle interlocking lever 140 is driven by the operation power as in the unlocked state. And the ratchet interlocking lever 130 rotates in the first rotation direction, and the holding of the slide door 90 by the latch / ratchet mechanisms 20K of the front door lock device 10A and the rear door lock device 10B is released. That is, in the vehicle door operation mechanism 100K of the present embodiment, if the in-vehicle operation handle 18 is opened, the slide door 90 can always be opened regardless of the door lock locking / unlocking state (the position of the connecting pin 134). It has become. At this time, the release motor 60 is actuated due to the opening operation of the in-vehicle operation handle 18, and the out-of-vehicle handle interlocking lever 120 is driven to rotate in the first rotation direction. The motor power of the release motor 60 is not transmitted to the ratchet interlocking lever 130 because the L-type second side path 123B moves while being held at the power cutoff position 133. That is, when the door lock is in the locked state, the closed holding of the slide door 90 is released only by the operation power generated by the opening operation of the in-vehicle operation handle 18.

  When the outside operation handle 17 is opened or remotely operated when the door lock is locked, the operation power or the motor power rotates the outside handle interlocking lever 120 in the first rotation direction. Since the connecting pin 134 moves in the L-shaped second side path 123B while being held at the power cut-off position of the I-shaped long hole 133, transmission of power from the vehicle handle interlocking lever 120 to the ratchet interlocking lever 130 is interrupted. The ratchet interlocking lever 130 remains at the origin position shown in FIG. Therefore, the closed holding of the slide door 90 by the front door lock device 10A and the rear door lock device 10B is maintained.

  Now, as shown in FIG. 11 and FIG. 12, the failure of the release motor 60 in a state where the vehicle exterior handle interlocking lever 120 and the ratchet interlocking lever 130 are located at the rotational end position away from the origin position in the first rotational direction. When the vehicle outside handle interlocking lever 120 and the ratchet interlocking lever 130 do not move due to an abnormality in the transmission path of the motor power or the like, the latch / ratchet mechanism 20K releases the closed holding of the slide door 90 (that is, the ratchet 30 is shown in FIG. 4 (the position indicated by the two-dot chain line).

  In such an emergency, the indoor lock operation unit 16 may be locked. Then, the connecting pin 134 moves from the power transmission position to the power cut-off position, and can move in the L-shaped second side path 123B in the L-shaped long hole 123 in the longitudinal direction. That is, the transmission of power from the vehicle exterior handle interlocking lever 120 to the ratchet interlocking lever 130 is cut off, and the release motor 60 having an abnormality in the motor power transmission path or the release motor 60 that has failed is disconnected from the latch / ratchet mechanism 20K. It is. Then, as shown in FIG. 13, the ratchet interlocking lever 130 is rotated in the second rotation direction by the urging force of the torsion coil spring 129 and returned to the original position. At this time, the connecting pin 134 moves in the L-type second side path 123B to the side away from the L-type first side path 123A while maintaining the power cutoff position of the I-type long hole 133. As a result, the open cables 91W and 92W are returned to the latch and ratchet mechanism 20K provided in the front door lock device 10A and the rear door lock device 10B, and the latch and ratchet mechanism 20K is held closed. It can be restored to a possible state.

  Further, the slide door 90 closed and held by the above-described release motor 60 disconnection operation can be opened by opening the in-vehicle operation handle 18 in the same manner as usual. That is, when the in-vehicle operation handle 18 is opened in a state after the out-of-vehicle handle interlocking lever 120 abnormally stops at the rotation end position and the motor disconnection operation is performed, as shown in the change from FIG. 13 to FIG. The in-vehicle operation handle 18 rotates in the first rotation direction and pushes the ratchet interlocking lever 130 in the first rotation direction. At this time, the connecting pin 134 moves in the L-type second side path 123B toward the L-type first side path 123A, so that the ratchet interlocking lever 130 rotates in the first rotation direction, and the open cable 91W. , 92W is pulled toward the remote control device 100, and the closed holding of the slide door 90 by the latch and ratchet mechanism 20K of the front door lock device 10A and the rear door lock device 10B can be released.

  As described above, according to the vehicle door operation mechanism 100K of the present embodiment, the indoor lock operation unit 16 that is normally used for the locking / unlocking operation of the slide door 90 is also used as the operation target of the motor separating operation. In the event of an emergency in which it is impossible to keep the slide door 90 closed due to a motor 60 failure or the like, the slide door 90 can be quickly closed by trial and error by operating the indoor lock operation unit 16 without examining the vehicle manual. It can be returned to a state where it can be held. In addition, since a tool is not required for the motor separating operation as in the prior art, the door can be quickly returned to a state where it can be kept closed. In addition, if the in-vehicle operation handle 18 is opened in the same manner as normal with the slide door 90 closed and held by the motor disconnection operation, the operation power is applied from the in-vehicle handle interlocking lever 140 to the ratchet interlocking lever 130. The closed holding of the slide door 90 is released, and the slide door 90 can be opened.
